Abstract
In order to correctly evaluate the damage of crew’s audio organ exposed in impulsive noise in armored vehicles as the weapon firing, the domestic and American Army’s evaluation methods for impulsive noise safety limit were mutually compared, and the differences of the two methods in the calculation of endure time of impulsive noise and permitted daily exposure times were analyzed. The impulsive noise at the crew’s ear position in the armored vehicles was tested when the weapon firing and the calculation results of the two evaluation methods were compared and analyzed. The test results show that the calculation results of the two evaluation methods have significant differences due to the different types of endure time used as one of the main influencing factors. The permitted daily exposure times from the domestic evaluation method is more conservative than that of the American Army’s method.关键词
